|  | Description: | 
|  | ------------ | 
|  |  | 
|  | Handheld devices from OneNetbook, AOKZOE, AYANEO, And OrangePi provide fan | 
|  | readings and fan control through their embedded controllers. | 
|  |  | 
|  | Currently supports OneXPlayer devices, AOKZOE, AYANEO, and OrangePi | 
|  | handheld devices. AYANEO devices preceding the AIR and OneXPlayer devices | 
|  | preceding the Mini A07 are not supportable as the EC model is different | 
|  | and do not have manual control capabilities. | 
|  |  | 
|  | Some OneXPlayer and AOKZOE models have a toggle for changing the behaviour | 
|  | of the "Turbo/Silent" button of the device. It will change the key event | 
|  | that it triggers with a flip of the `tt_toggle` attribute. See below for | 
|  | boards that support this function. |
